Description
2 REJECT #1 Level Active when Leak Rate is over set point #1.
14 Ready Level Active when Fil and Turbo ok, i.e., the system is ready to test.
15 Zeroing Level Active when performing a ZERO function.
16 Leak Rate
Update Valid data on BCD when low, becomes active during the time that
the BCD leak rate output is updated.
17 Filament Fault Level Active when selected Ion Source Filament is non-functional.
18 CAL OK Level Active when last calibration ok. It is set inactive at the start of a
CALIBRATE routine and at power on.
22 Calibrating Level Active when performing a CALIBRATE routine.
26 REJECT #2 Level Active when Leak Rate is greater than set point #2.
27 +V Input N/A Customer-su5 to +24 VDC for J3.
28 +V Input N/A Customer-su5 to +24 VDC for J3.
29 REJECT #3 Level Active when Leak Rate greater than set point #3.
30 REJECT #4 Level Active when Leak Rate greater than set point #4.
33 HiVac OK Level Active when turbo is ok.
31 Analog Output Analog Analog Leak Rate output voltage.
32 Analog Return Ground Analog Leak Rate output voltage return.
